' a [The invention i's'shownand describedin {da 'nectionwith'an ice-chute and bed for supporting the icecake during the-operation oi cutting and trimming:

will be convernent for operation-1 i v I The invention includes scoring or'formation of The principal objectsin view have beenft'o pros vide a machi'ne of fewandsimple parts to-occupy' I a limited space'in' a'n-ic'e plant,"-jand will -require, a limited power for o 'aeration",will form-perfect ice-blocks rapidly, and will consistroi parts which transversely disposed grooves in the elongatedice cakes as well as theforination'of blocks or cubes.

The invention consists, broadly, of a'vertieally movable carrier, casing 'orhousing-cap; of tree'- ,f tangular form, in plan, forcontaining practically all of the mechanism; said ousing-cap oricarrier and ice-cutting m'echanismtherein and thereon 1 being counterbalanced. for convenience; and

adapted tohave downward sliding movements in vertical'guidesfor cutting and trimming; and to have upward sliding movementsfrom' an ice-sup porting bed to-permit removal of ice cubes and anintake of uncut ice cakes; the feature of coun' terbalancing being depended upon' for easy man-ehandleyflfi secured to the front-end, 'any'suitable arrangement of parts maybe provided; such as ual control.

The invention employs a vertically movable carrier or housing-cap of box-formg'open at its hottom and provided with "an 7 endwall opening for receivingan uncut ice cake-from an ice-chute,and

includes automatic means for closing said open ing. The invention also includes an ice-trimmer which operates automaticallyg With the foregoing objectsin .view vand others hereinafter to appear, the invention presents a new-and useful construction, combinationand' arrangement vof parts as described herein and claimed and as illustrated in the accompanying drawings, it being 'understood that changes may be'made in forin; size; proportionsiand minor details as may be found of; advantage',' "said changes being within the scopev o'f the invention asclaimedfi In the drawingaliig, 1-is aviewoftheinvention'} in front elevation; the carrier or housing-cap" be ing disposed in itslowermost position. i
